The turkey is a quintessentially American bird, exported from the New World like corn and potatoes. But the turkey is not native to the Pacific Northwest. The wild turkeys you may have seen here are part of the bird’s comeback story.

Forest and park rangers on Washington's Olympic Peninsula say they've reduced the risk from aggressive mountain goats. They did it by hazing the animals for much of the summer. Olympic National Forest reopened a popular hiking trail Monday. Correspondent Tom Banse has the story from Mount Ellinor, near Hoodsport, Washington.

For the past three months, the steep trail up Mount Ellinor has been closed. The reason for that is that multiple hiking parties reported feeling threatened by insistent mountain goats.

When the Clean Water Act was created 40 years ago rivers were on fire and raw sewage was spilling into some waterways. The Act has accomplished a lot over the years - reining in the largest industrial polluters and improving water quality, overall.

But there are some emerging contaminants the Clean Water Act was never designed to control, and they are affecting the environment in new and different ways. Ashley Ahearn has the latest installment in our ongoing EarthFix series “Clean Water: The Next Act."

The Washington Department of Fish and Wildlife has re-issued the kill order for four wolves in a pack in the Northeastern corner of the state. Starting Wednesday marksmen will take to the field, Ashley Ahearn reports.

State officials have called off orders to kill four members of a wolf pack in Northeastern Washington. Ashley Ahearn reports.

National park officials have abruptly closed Crater Lake to scuba divers. They say they need time to develop rules to keep invasive species out of the Southern Oregon lake. Amelia Templeton of Earthfix reports.

Scuba diving in Crater Lake is tricky. The lake sits on the Cascade crest at about 6,000 feet. So divers have to take precautions to handle the elevation. And then there’s the steep, rocky trail to the lake shore. Diver Walt Bolton says it’s worth the hike.
